Abstract: A jig for cutting plugs for pocket holes from a workpiece has a base leg, from which transversely extend guide and clamp legs. One or more guide channels extend through the guide leg at an angle to an interior face of the guide leg to guide the sleeve of a rotating cutter bit that has a cutting edge at its end and a removed section forming a cutting blade. A clamp extends from the clamp leg to engage one face of a workpiece whose end is mounted on a raised ledge on the base leg and holds the workpiece opposing face against the guide leg interior surface as the sleeve end cutting edge and blade advances into and cuts entirely through the workpiece to cut the plug. A collar on the cutting bit shaft engages the guide leg to prevent the sleeve end cutting edge from contacting the base leg. The jig also can be used for making pocket holes by using the appropriate drill bit.

Abstract: A dowel jig for making holes in a member such as a board to accept dowels for projecting toward corresponding holes for receiving the dowels to make butt, end and T type dowel joints for two members. The jig has a base having an internal planar area and at least one hole transversely through the planar area and a transverse leg at each end of the base. A foot is at the outer corner junction of each base end and transverse leg and the lower surfaces of both feet lie in a common plane that is parallel to the base internal planar area so that when the lower surfaces of the feet are placed on the flat upper surface of a member the base hole will be transverse to the flat surface to permit aligned passage of a drill bit to drill a hole in the member transverse to the flat surface. Notches are provided in each of the feet along a line that passes through the hole center to hold a rod in which a hole is drilled.

Abstract: A clamp to make a straight edge on a working board has a base with a lower surface to slide on a table saw and a main wall that extends upward from the base. A lower support extends outwardly from the main wall in opposite directions, and two upper supports extend outwardly from the main wall in opposite directions to define channels, wherein a reference board is placed in one channel and the working board in the other channel. A shim arm is pivotally mounted to and extends along the base. A shim support pad is mounted at the free end of the arm and its upper surface is in the same plane as the upper surface of the base. The shim arm swings out from the base so that the pad forms a support on which the working board rests to effectively increase the width of the base.
